Toshiba readying Radeon HD 3800-equipped Dynabook TXW/69DW?

We already knew Toshiba's Dynabook TXW/69DW came loaded with an ATI Mobility Radeon HD 2600 GPU, but according to AVing, Japan could be seeing a revamped iteration that includes the HD 3800. Moreover, the 15.4-inch machine would boast an Intel Core 2 Duo T7500 CPU and PM965 Express chipset, but we're left to wonder if any of the other critical components would be upgraded, too. Nevertheless, it seems that a price / release date is also uncertain, but if you just so happen to peep one of these in downtown Tokyo, be sure to holler in comments.
